I donned more PPE and went at it with a grinder and wire wheel. The wires are pretty firm. I pushed down as much as I could, essentially trying to see in the limited space, what was solid and what wasn’t. I found that most of it didn’t get better. It is firm, reasonably solid, and doesn’t really grind down any more. Where there was lose material, I pushed through it and ground back to firm areas where material no longer was easily removed.
It doesn’t look a lot different than the first few minutes. I think I need some tiny roloc discs to fit in the small spaces where the rust is.
I’m also thinking that perhaps I should shape to the exterior of the vehicle, grind the paint underneath with a grinder and/or vacuum-attached sander, and have a much larger, broader area to bond to. Then I can also patch to the topside if I choose. Essentially a fully sealed metal sandwich. I think I’ll get to bright metal easier underneath. It’s fully accessible.
I actually consumed a few wire brushes, but couldn’t progress any further. They don’t scuff to bright metal I guess.
Red scotch brite also couldnt cut enough to get it bright.
